What makes the current situation unsustainable, in your view?
Africa has a population of 1 billion, projected to grow to 4 billion by century's end. Wars throughout the Middle East and the subsequent refugees don't seem likely to stop.
Europe's population is about 600 million. There is a practically endless supply of people who would like to leave their countries and come to Europe.
Option one is Europe continues to allow this, and is eventually turned into something resembling the very countries these people are fleeing.
Or, Europeans could actually stop the flow of immigrants and preserve a Europe populated by Europeans.
It is an event not unlike the conquest of the Americas by Europeans in terms of the importance for the future of a people. This Italian political ad sums it up well:
"They allowed immigration, now they live on reservations"
Leftists like you think it's a crime for Europe to want to remain European and not turn into Syria+Somalia.
